Abstract

Disclosed is a method for inputting graphical information into a computer system. The graphical information may arise when a drawing device is moved relative to a base having a position-coding pattern detectable by an optical sensor in the drawing device. The computer system may record position information arising from a first area of the base as graphical input while recording position information arising from a second area of the base as the selection of a property associated with the graphical input. Such a property may be a visual property, such as line type, line thickness, and color.
